    automake: fixups for read_am_file() and calling code
    
    * automake.in (read_am_file): Adjust function prototype (was
    requiring only two arguments, rather than three).  Rename the
    parameter '$curdir' to the more correct '$reldir'.  Rename the
    local variable '$cur_dir' to the more appropriate and less
    confusing '$reldir_canon', and avoid continuously re-computing
    it in the loop on input lines, since it is fixed per-Makefile.
    When processing an include directive, store the computed new
    relative dir path in a variable named '$new_reldir' rather than
    '$new_curdir'.

    NEWS: improve wording about new {RELDIR} preproc support

    preproc: better (long) name for built-in '{...}' substitutions
    
    Rename them like this:
    
      * {CURDIR} => {RELDIR}
      * {CANON_CURDIR} => {CANON_RELDIR}
    
    The name "CURDIR" was a little ambiguous and potentially confusing,
    because it could get mixed up with the concept of "current directory"
    for the executing recipes (which will generally not be the same as
    the '{CURDIR}' expansion, of course), as well as with the GNU make
    predefined variable '$(CURDIR)'.  In addition, the '{RELDIR}' name
    seems more faithful to the intended semantics of the substitution.

    preproc: prefer '{D}' over '&{D}&' (and similarly for other substs)
    
    The new form is shorter, easier and more natural to type, and less
    likely to get wrong due to typos or distractions.  Such issues with
    the '&{FOO}&' form (originally suggested by myself, oops) have been
    made clear and evident by the recent work on the tests checking the
    new preprocessing features (see previous commit 07f3534f).
    
    * automake.in (read_am_file): Adjust.

    preproc: enhance and extend tests
    
    * t/preproc-demo.sh: New test, a "demo" of how the new pre-processing
    feature could be used in a real-world package.
    * t/preproc-errmsg.sh: New test, check that error messages remain
    useful when the new pre-processing features are involved.
    * t/curdir.sh: Split up ...
    * t/preproc-basics.sh, t/preproc-c-compile.sh: ... into these two
    tests, with some refactorings, clean-up and enhancements.
    * t/list-of-tests.mk: Adjust.

commit 85c3f473bb51dc48c51fa18665cfcfdc1b128faa
Author: Peter Rosin <address@hidden>
Date:   Sun Jan 27 00:48:28 2013 +0100

    preproc: add support for relative names in included fragments
    
    The rationale for this change is that it is annoying to have
    to repeat the directory name when including a Makefile fragment.
    For deep directory structures these repeats can generate a lot
    of bloat.  It also hinders reuse and easy directory restructuring
    if all Makefile fragments have to know exactly where they live.
    
    Suggested by Bob Friesenhahn, and later discussed in bug#13524.
    
    * automake.in (read_am_file): Add third argument specifying the
    relative directory of this Makefile fragment compared to the
    main Makefile.  Replace &{CURDIR}& and &{CANON_CURDIR}& in the
    fragment with this relative directory (with slashes etc, or
    canonicalized).
    (read_main_am_file): Adjust.
    * t/curdir.sh: New test.
    * t/list-of-tests.mk: Augment.
    * doc/automake.texi (Include): Document the new feature.
    NEWS: Add new feature.
